I am trying to grant access to users that subscribe to premium on the iOS app also to users that use the macOS version.
The iOS and macOS version are two separate apps with different BundleIDs, same Team ID.
I can't create a App bundle because they are part of different platforms. I know that I could ask the user for a login so I could recognize the user from the authentication, but I would like to avoid this step.
Is there any ID i can use to identify users between different platforms?
